Let’s change the example of the previous section by using a block helper named studyStatus but with the same context variable: Handlebars. This options object has a fn() method that allows us to change the context of the object temporarily to access a certain property. When we register a custom block helper, Handlebars automatically adds an options object as the last parameter to the callback function. The variables are written in double curly braces In the first case, they appear inside the tag with a type='text/x-handlebars-template' attribute and an ID. Templates can be written both in the HTML file or separately. I hope that this short recap helps you in deciding if it’s worth using Handlebars or not.

It’s used in popular frameworks and platforms such as Ember.js, Meteor.js, Derby.js and Ghost.

It simplifies the task of manually updating the data on the view.

It keeps your HTML page clean and separates the logic-less templates from the business logic in your JavaScript files, thus improving the structure of the application (and also its maintainability and scalability).

If you’re asking why you should employ this templating engine rather than another one, you should take a look at its pros. Handlebars can be loaded into the browser just like any other JavaScript file: As a matter of fact, we can say that Handlebars is a superset of Mustache. Mustache is fully logic-less but Handlebars adds minimal logic thanks to the use of some helpers (such as if, with, unless, each and more) that we’ll discuss further in this article.

It’s an extension of Mustache with a few additional features. Handlebars is a logic-less templating engine that dynamically generates your HTML page.
